Above Runs are comparing the Standard DOM 3.0R to the New DOM 3.0 XT-R with Billet Compressor Wheel and 10cm2 Turbine Housing. Both runs are on 93 octane and both cars have similar mods. Note that the with the new lightweight Compressor Wheel the XT-R spools faster!

Above Run is on VP Q16. You will note that we shut to car down early because the clutch let loose. The peak HP numbers are not quite accurate. The car however, was on point to make about 465whp.

Almost 30F difference on a uncorrected chart... Also, did your atmospheric pressure sensor broke or something? 29.07 in-Hg ... that's too low. Did a hurricane went through your area? lol

Can you put the same chart... but this time add the SAE correction factor to it. Basically the 409WHP graph will come down... while the 360WHP graph goes up. 30F will do that! As far as the spool there's too many variables.

In paper what should happen between these 2 turbos is that the new xtr should make around 20-25 whp more at the same boost level (52 lb/min vs 55 lb/min). But it should spool just as fast or slower than the old DOM3 (10cm turbine, ligther but bigger compressor wheel)

Do you guys think on a 2002 JDM 2.0L with AVCS, with a good tune and all the supporting mods except cams, do you think the Dom 3XTR is capable of making 450whp on VP C16? Also, on pump 95, is it capable of making 400whp? We have terrible 91 gas here but I have been thinking about mixing 100 unleaded to get the octane up to 95.

I ran 28-30psi on 93 for 40k on a Subaru 500+whp.. Its not out of the question. Been doing it on DSMs since back in like 2000.

As for the turbo's they look decent. I still think for all the money you spend setting up a stock location you can do a nice rotated and be done with it... also have no real limitation on turbo/back housings selection.

i put an extra spring in my Tial Ext wastegate last night to have 20psi spring combo on my STI with OG Green and after the install my boost is pegging at 30psi on my STRi gauge. also on 91+meth. but the logger was only peaking at 28 psi.

And my external wastegate is no longer opening......kind of concerning me......but i picked up 2psi with the mbc in the same spot.

26lbs on pump is ludicrous... But fun for how ever long it's going to last.

19.5psi on ATP35R is ludicrous

I disagree on the rotated part, if anyone is planning on running no more than 35R .63/.82 AR POWER this is the perfect turbo IMO. The DOM 3.0XT-R 2.4" inlet is putting down about the same whp and at about the same boost level with the same gas as IAG's rotated 35R.

Most of us will only need a bigger CAI and it seems that there is no need for EWG
